Every online transaction is having credit debit
transactions. Suppose if client is transferred money from
his account to another account. The client account will be
debited and other party account will be credited.
If we are maintaining only client account from our end.
These transactions details will be updated/inserted into
database tables. This can be achieved by writing pl/sq l
program unit
can be called from other interfaces.

I think this is a normal process for testing what we do for
pl/program units.

When client performs online transaction back end pl/sql
program unit will be called and the corresponding data base
will be effected.

type type_name is table of varchar2(30) index by binary_integer for the above type you have to create a identifier... like identifier_name type_name; for the above type you can use the below methods..like first , last , prior, next , delege..etc...like this.. if you create a cursor...like cursor cursor_name is select * from scott.emp; is there any methods like above to use prior, fist , last , next , trim ,etc...
